Improvement in faucets



UNITED STATES FIG JOHN G. L. BOETTOHER, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN FAUCETS.

Specification forming part of Detters Patent No. 162,605, dated April27, 1875; application filed March 24, 1875.

of Vwhich the following is a specification:

This invention is illustrated in the accompanying drawing, in which-Figure l represents a longitudinal central section. Fig. 2 is atransverse section in the plane a' x, Fig. 1. Fig. 3 is a section of theshank detached. Fig. 4 is a perspective view, illustrating theapplication of my invention.

Similar letters indicate corresponding parts.

This invention relates to an improvement in that class of faucets whichare provided with a vent-channel, so that when the faucet is applied toa closed barrel or vessel, and said faucet is opened for the purpose ofdrawing out the contents of said vessel, the external air is free toenter through the ventchannel, and the liquid ilows freely.

My invention consists in constructing the hollowr shank of a faucet witha screw-threaded projection, a corrugated discharge-nipple beingconnected with said projection by means of a coupling-nut.

From the projection on the shank extends a vent-tube projecting backwardthrough the shank, and a check-valve being arranged at the rear end ofthe'shank, all in such a manner as will be fully hereinafter described,when `the faucet is secured in a barrel or other closed vessel, and thedetachable nipple is connected with a fountain containing carbonic-acidor other gas under pressure.

The liquid from the barrel will discharge, when the faucet is opened, assoon as the pressure in the barrel becomes less than that of the gas inthe fountain. rlhe gas forces the check-valve oft from its seat at therear end of the shank, and passes through the liquid into the barrel.

In the drawing, the letter A designates a faucet, from the tubular shankB of which extends a projection, et, through which extends a channel, b,that connects with a pipe, c, situated in the interior ot' the shank.With the projection a is combined a nipple, d, which is secured inposition by a coupling-nut, c, and which is intended to receive a pipeof indiarubber or other suitable material extending from andcommunicating with a fountain containing carbonic-acid or other gasunder pressure, said detachable nipple serving to make this connectionwith ease and facility. Said pipe c extends close to the end otl theshank B, and it is provided with an enlargement, f, forming a chamberfor the reception of a valve, g, which is held in its seat by thepressure ot' the liquid in the barrel or vessel to which the faucet maybe attached. rlhe valve-chamber f is partly cut away, so that the liquidfrom the barrel can pass more freely through the faucet when the plug isopened. A perforated cap, h, closes the end of the shank, and protectsthe valve and the valvechamber.

After the faucet is secured in a barrel or closedvessel containing beeror other liquid, I connect the nipple d with a fountain containingcarbonic-acid or other gas under pressure; and if the faucet is opened,the liquid from the barrel discharges as long as the pressure in saidbarrel exceeds the atmospheric pressure; but whenever the pressure inthe barrel becomes lower than that in the fountain connected to thenipple d, the carbonicacid or other gas contained in said fountain opensthe valve g, and passes through the beer into the barrel. By these meansthe pressure in the barrel is kept at a uniform point, and the life ofthe beer is constantly renewed.

The shank B may be made detached from the faucet, as shown in Fig. 3, sothat any common faucet can be secured in said shank, which latter isprovided with the detachable nipple d, vent-pipe c, and valve g.

The discharge-spout of my faucet is provided with a trap, i, which isformed as shown in Fig. l of the drawing, so that when the plug of thefaucet is closed the liquid still contained in the spout is sucked backinto said trap, and the dripping of the faucet is prevented.

barrel is shown in Fig. 4.
